I think the Outfit is around 50 made guys/full time soldier associates and 100 associates. About 30 of those 50 are active.

As for structure, there is definitely a distinction between Cicero, 26th St and Grand Ave/Elmwood. Whether EP is active and Cicero is actually 2 or 3 crews, who knows.

As for who is in charge, it's well known that Frank Caruso runs 26th St. As to the rest, no one really knows for sure.
